Wooden Spoon
A wooden spoon is a Kitchen utensil, utensil commonly used in food preparation. In addition to its culinary uses, wooden spoons also feature in folk art and culture. History The word ''spoon'' derives from an ancient word meaning a chip of wood or horn carved from a larger piece. Wooden spoons were easy to carve and thus inexpensive, making them common throughout history. The Iron Age Celts () of Britain used them. This is evidenced by an example of a small ladle discovered during archaeological excavations at the Glastonbury Lake Village. Roman period spoons have been recovered from excavations in the City of London. The Anglo Saxons were great workers of wood, as were the Vikings, and both these groups of settlers to the British Isles produced wooden spoons for domestic uses. Uses Practicality Cooking Today, wooden spoons in western cultures are generally medium to large spoons used for mixing ingredients for cooking or baking. They may be flat or have a small dip in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Kitchen Utensil
A kitchen utensil is a small hand-held tool used for food preparation. Common kitchen tasks include cutting food items to size, heating food on an open fire or on a stove, baking, grinding, mixing, blending, and measuring; different utensils are made for each task. A general purpose utensil such as a chef's knife may be used for a variety of foods; other kitchen utensils are highly specialized and may be used only in connection with preparation of a particular type of food, such as an Separating eggs, egg separator or an apple corer. Some specialized utensils are used when an operation is to be repeated many times, or when the cook has limited dexterity or mobility. The number of utensils in a household kitchen varies with time and the style of cooking. A cooking utensil is a utensil for cooking. Utensils may be categorized by use with terms derived from the word "wikt:ware#English, ware": kitchenware, wares for the kitchen; ovenware and bakeware, kitchen utensils that are for ...

Onion
An onion (''Allium cepa'' , from Latin ), also known as the bulb onion or common onion, is a vegetable that is the most widely cultivated species of the genus '' Allium''. The shallot is a botanical variety of the onion which was classified as a separate species until 2011. The onion's close relatives include garlic, scallion, leek, and chives. The genus contains several other species variously called onions and cultivated for food, such as the Japanese bunching onion '' Allium fistulosum'', the tree onion ''Allium'' × ''proliferum'', and the Canada onion '' Allium canadense''. The name '' wild onion'' is applied to a number of ''Allium'' species, but ''A. cepa'' is exclusively known from cultivation. Its ancestral wild original form is not known, although escapes from cultivation have become established in some regions. The onion is most frequently a biennial or a perennial plant, but is usually treated as an annual and harvested in its first growing season. ...

Khokhloma
Khokhloma (also Hohloma, Russian: хохлома; Russian pronunciation: əxɫɐˈma or Khokhloma painting (хохломская роспись, ''hohlomskaya rospis'') is a style of Russian art traditionally painted on wooden household items. It is known for its curved linear features depicting vivid small flowers, berries, grasses, and leaf motifs. The Firebird, a common and popular figure from the Russian fairytales is often featured as the main subject matter. The style is named after the village of Khokhloma (56.973°N 43.902°E) in Koverninsky District, Nizhny Novgorod Oblast, Volga region, where it first appeared in the second half of the 17th century. This region is known for wood crafts ranging from small household goods to carvings on gables and gates in the traditional peasant cottages. The abundance of timber made for prolific and notable woodcarving traditions emerge throughout the centuries. Alongside Khokhloma, there are other wood painting styles and traditio ...

Wood Grain
Wood grain is the longitudinal arrangement of wood fibers or the pattern resulting from such an arrangement. It has various derived terms refer to different aspects of the fibers or patterns. Wood grain is important in woodworking and it impacts aesthetics. Definition and meanings Wood grain is the longitudinal arrangement of wood fibers or the pattern resulting from such an arrangement. R. Bruce Hoadley wrote that ''grain'' is a "confusingly versatile term" with numerous different uses, including the direction of the wood cells (e.g., ''straight grain'', ''spiral grain''), surface appearance or figure, growth-ring placement (e.g., ''vertical grain''), plane of the cut (e.g., ''end grain''), rate of growth (e.g., ''narrow grain''), and relative cell size (e.g., ''open grain'').Hoadley, R.

Rancidification
Rancidification is the process of complete or incomplete autoxidation or hydrolysis of fats and oils when exposed to air, light, moisture, or bacterial action, producing short-chain aldehydes, ketones and free fatty acids. When these processes occur in food, undesirable odors and flavors can result. In processed meats, these flavors are collectively known as warmed-over flavor. In certain cases, however, the flavors can be desirable (as in aged cheeses). Rancidification can also detract from the nutritional value of food, as some vitamins are sensitive to oxidation. Similar to rancidification, oxidative degradation also occurs in other hydrocarbons, such as lubricating oils, fuels, and mechanical cutting fluids. Pathways Five pathways for rancidification are recognized: Hydrolytic Hydrolytic rancidity refers to the odor that develops when triglycerides are hydrolyzed and free fatty acids are released. This reaction of lipid with water may require a catalyst (such as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Polymerize
In polymer chemistry, polymerization (American English), or polymerisation (British English), is a process of reacting monomer molecules together in a chemical reaction to form polymer chains or three-dimensional networks. There are many forms of polymerization and different systems exist to categorize them. In chemical compounds, polymerization can occur via a variety of reaction mechanisms that vary in complexity due to the functional groups present in the reactants and their inherent steric effects. In more straightforward polymerizations, alkenes form polymers through relatively simple radical reactions; in contrast, reactions involving substitution at a carbonyl group require more complex synthesis due to the way in which reactants polymerize. As alkenes can polymerize in somewhat straightforward radical reactions, they form useful compounds such as polyethylene and polyvinyl chloride (PVC), which are produced in high tonnages each year due to their usefulness in ...

Flax Oil
Linseed oil, also known as flaxseed oil or flax oil (in its edible form), is a colorless to yellowish oil obtained from the dried, ripened seeds of the flax plant (''Linum usitatissimum''). The oil is obtained by pressing, sometimes followed by solvent extraction. Owing to its polymer-forming properties, linseed oil is often blended with combinations of other oils, resins or solvents as an impregnator, drying oil finish or varnish in wood finishing, as a pigment binder in oil paints, as a plasticizer and hardener in putty, and in the manufacture of linoleum. Linseed oil use has declined over the past several decades with increased availability of synthetic alkyd resins—which function similarly but resist yellowing.

Walnut Oil
Walnut oil is oil extracted from walnuts, ''Juglans regia''. The oil contains polyunsaturated fatty acids, monounsaturated fatty acids, and saturated fats. Composition According to gas chromatographic and HPLC analysis, virgin walnut oil consists of linoleic acid (60–62%). It also contains many phenolc compounds including γ-tocopherol, tanins, and flavanoids. Several of these exhibit antioxidant properties. According to another source, walnut oil is composed largely of polyunsaturated fatty acids (72% of total fats), particularly alpha-linolenic acid (14%) and linoleic acid (58%), oleic acid (13%), and saturated fats (9%). Walnuts typically contain high concentrations of phenolics including ellagic acid. Culinary use Walnut oil is edible and is generally used less than other oils in food preparation, often due to high pricing. It is light-coloured and delicate in flavour and scent, with a nutty quality. Although chefs sometimes use walnut oil for pan-frying, most ...

Hempseed Oil
Hemp oil (hemp seed oil) is oil obtained by pressing hemp seeds. Cold pressed, unrefined hemp oil is dark to clear light green in color, with a nutty flavor. The darker the color, the grassier the flavour. It should not be confused with hash oil, a tetrahydrocannabinol-containing oil made from the ''Cannabis'' flower. Description Refined hemp seed oil is clear and colorless, with little flavor. It is primarily used in body care products. Industrial hemp seed oil is used in lubricants, paints, inks, fuel, and plastics. Hemp seed oil is used in the production of soaps, shampoos and detergents. The oil has a 3:1 ratio of omega-6 to omega-3 essential fatty acids. It may also be used as a feedstock for the large-scale production of biodiesel. Manufacture Hemp seed oil is manufactured from varieties of ''Cannabis sativa'' that do not contain significant amounts of tetrahydrocannabinol (THC), the principal psychoactive element present in the cannabis plant. This manufacturing proce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Drying Oil
Drying is a mass transfer process consisting of the removal of water or another solvent by evaporation from a solid, semi-solid or liquid. This process is often used as a final production step before selling or packaging products. To be considered "dried", the final product must be solid, in the form of a continuous sheet (e.g., paper), long pieces (e.g., wood), particles (e.g., cereal grains or corn flakes) or powder (e.g., sand, salt, washing powder, milk powder). A source of heat and an agent to remove the vapor produced by the process are often involved. In bioproducts like food, grains, and pharmaceuticals like vaccines, the solvent to be removed is almost invariably water. Desiccation may be synonymous with drying or considered an extreme form of drying. In the most common case, a gas stream, e.g., air, applies the heat by convection and carries away the vapor as humidity. Other possibilities are vacuum drying, where heat is supplied by conduction or radiation (or micr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Scrambled Eggs
Scrambled eggs is a dish made from eggs (usually chicken eggs), where the whites and yolks have been stirred, whipped, or beaten together (typically with salt, butter or oil, and sometimes water or milk, or other ingredients), then heated so that the proteins denature and coagulate, and they form into " curds". History The earliest documented recipe for scrambled eggs was in the 14th-century Italian cookbook ''Libro della cucina''. Preparation Only eggs are necessary to make scrambled eggs, but salt, water, chives, cream, crème fraîche, sour cream, grated cheese and other ingredients may be added as recipes vary. The eggs are cracked into a bowl with salt and pepper, and the mixture is stirred or whisked. Alternatively, the eggs are cracked directly into a hot pan or skillet, and the whites and yolks stirred together as they cook. In ''Food in England'' (1954) Dorothy Hartley comments, "There are two main schools: one (which I believe to be correct) breaks in the e ...
